The 20 kA figure under 60947-2 is the one that matters for industrial panel coordination — it tells you the breaker can safely interrupt a fault current up to 20 kA without welding its contacts or rupturing, which is enough headroom for most secondary distribution panels fed from a transformer in the 500–1000 kVA range. Under UL 1077 / CSA C22.2 No.235 it's rated 5 kA, so if your BOM calls for a UL 489 listed branch breaker, this isn't that — it's a supplementary protector per UL 1077. The sealable option (padlockable toggle) lets you lock it in the OFF position for lockout/tagout — a practical detail for maintenance isolation on a conveyor zone or machine cell. ## Environmental range and derating But the humidity derating matters: max 95% RH up to 55 °C, then it drops to 55% at 70 °C and 35% at 75 °C. ## Compliance and material notes Complies with IEC/EN 60898-1 and IEC/EN 60947-2, plus UL 1077 and CSA C22.2 No.235 for North American supplementary protection.","metaTitle":"Siemens 5SY4332-6 SENTRON MCB, 3P, B-Curve, 10kA IEC, 20kA I","metaDescription":"Siemens 5SY4332-6 SENTRON miniature circuit breaker, 3-pole, B-curve, 10 kA per EN 60898-1, 20 kA per IEC 60947-2.
